Subject: [PATCH v2 3/6] phy: qcom-qmp: add QMP V2 PCIe PHY support for ipq60xx
Date: Wed, 5 May 2021 12:18:31 +0300 [thread overview]
Message-ID: <e24f2bedb8a7346018b58136bcb0a4004d8677a0.1620203062.git.baruch@tkos.co.il> (raw)
In-Reply-To: <cover.1620203062.git.baruch@tkos.co.il>
From: Selvam Sathappan Periakaruppan <speriaka@codeaurora.org>
Based on code from downstream Codeaurora tree. The ipq60xx has one gen3
PCIe port.

Subject: [PATCH v2 3/6] phy: qcom-qmp: add QMP V2 PCIe PHY support for ipq60xx
Date: Wed, 5 May 2021 12:18:31 +0300 [thread overview]
Message-ID: <e24f2bedb8a7346018b58136bcb0a4004d8677a0.1620203062.git.baruch@tkos.co.il> (raw)
In-Reply-To: <cover.1620203062.git.baruch@tkos.co.il>
From: Selvam Sathappan Periakaruppan <speriaka@codeaurora.org>
Based on code from downstream Codeaurora tree. The ipq60xx has one gen3
PCIe port.

Subject: [PATCH v2 3/6] phy: qcom-qmp: add QMP V2 PCIe PHY support for ipq60xx
Date: Wed, 5 May 2021 12:18:31 +0300 [thread overview]
Message-ID: <e24f2bedb8a7346018b58136bcb0a4004d8677a0.1620203062.git.baruch@tkos.co.il> (raw)
In-Reply-To: <cover.1620203062.git.baruch@tkos.co.il>
From: Selvam Sathappan Periakaruppan <speriaka@codeaurora.org>
Based on code from downstream Codeaurora tree. The ipq60xx has one gen3
PCIe port.
